MACHINE FOR Sl-IAPING'HEELS.

SPECIFICATION forming part of Letters ratent No. 761,485, dated May 31,1904.

Application filed May 6, 1901.

To ai whom it may concern:

Be it known that I, J on J HEYS, of Lynn, in the countyloflEsse andState of Massachusetts, have invented certain. new and usefulImprovements'in Machines for Shaping- Heels, of which the following is aspecification.

This invention relates to a new and improved apparatus for shaping theupper surfaces of heels; and it consists in the novel features andrelative arrangement of parts hereinafter fully described in thespecification, clearly illustrated in the drawings, and particularlypointed out in the claims. I 1

Reference is to be had to the accompanying drawings, forming a part ofthis application, wherein like characters are usedto indicate likepar'tswherever they occur.

blank resting upon adjusting-plates 23 upon the bed-plate and beingengaged by the walls The jaw 22 is .formed- 'with ears 29. 30 representsa vertical stud carried by a socketpiece 31 upon the, top oftlieStandard. 32 represents-a sleeve arrangedto slide upon said stud.Thissleeve is formed with ears 33 and 8c; The clamps 23 and 27 arearranged to hold a heel-blank 28 between them, the heela depending arm34. (See Figs. 1, 2, and 8.) A link 35 is pivoted at one end to the ears33 and at its opposite end to the ears 29, whereby ,as the sleeve 32 ismoved up or down the jaw 22 will be advanced toward or withdrawn fromits complemental jaw 24 to grip or release the heel 28. A bracket 36 issecured by bolts 37 to the under side of the top of the standard 1beneath the socket-piece 31. (See Figs. 1 and 2.) A rod 38 is arrangedat its upper end to slide in a bearing in said bracket 36. A fork 39 issecured to the lower end of said rod and positioned to engage andstraddle the main shaft 7. A roller 40 upon said fork engages the cam 9,while a spring 41 upon the rod 38 and arranged between the bracket 36and a collar 42 upon said rod serves to keep the roller 40 in engagementwith the cam. In other words, the cam 9 raises the rod, while the spring41 depresses said rod when released by the cam 9. The arrangement issuch that the gripping ction of the jaws is caused by the spring and thereleasing action by the cam 9. As the spring 41 pulls down the sleeve 32the link 35 is straightened to clamp the heel 28. The sleeve 32 and link35 act like a toggle; but owing to the action of the spring 41 thetoggle is set with a yielding action.

A crank is secured to the gear 8. A bracket 51 is secured to the top ofthe standard 1 and projects over the to thereof. 52 represents a pintlemounted in the free end of said bracket.

53 represents a link pivoted at one end upon the pintle 52, while at itsopposite end it car ries a bearing for a pintle 54. A bell-crank isrigidly secured to one end of the pintle 54 and comprises two arms 5556. A rod 57 is connected at its lower end to the free end of the crank50 and at its upper end to the free end of the arm 56, whereby a rockingmotion is imparted to the pintle 54. A slotted link or guide 58 (seeFig. 3) is pivoted midway of its ends upon the jaw 24. Set-screws 60,carried by the lugs 61 upon the link or guide 58, are arranged'to engagethe jaw 24, whereby the plane of the slot of said guide 58 may be variedand adjusted. A roller 62'upon the free end of the arm 55 of thebell-crank is arranged in the slot of the guide 58 and by its travel insaid slot causes the pintle 54 and the cutter, hereinafter described,carried by said pintle to travel in a predetermined path with respect tothe plate 21 and the heel 28 supported thereby. By this construction thedegree and plane of the cut made in the heel 28 may be varied asdesired. The slot in the guide 58 may be curved, as shown, or may haveany preferred plane, whether curved or straight.

A lever 7 O is secured at one end to the pintle 54 and is moved thereby.Arms 71 are formed upon the free end of said lever. 72 represents aknife secured at its edges to said arms 71, the cutting edge of saidknife being at the right in Figs. 5 and 6. A rod 73 is secured bycountersunk screws 74 to the upper surface of the knife.

75 represents a block formed with a recess in which is arranged the rod73, the block being cut away above the knife, as shown, to permitvertical movement of the knife.

76 represents an ad justing-screw secured at one end to said block andat its other end to the lever. By this construction the plane of theknife in cross-section may be adjusted as desired.

As shown in Figs. 5 and 9, the adjustingscrew 76 is a right and lefthand screw, one end fitting in the body of the lever 70 and the otherend fitting in the block 75. Said block is formed with wings or groovedlugs which embrace the arms 71 of the lever 7 0, whereby said block isguided when adjusted by the screw. The rod 73, to which the knife 7 2 issecured, as above stated, is inserted endwise into the recess abovementioned as formed in the block 75, said recess being contracted at thelower end 0 face of the block, so as to prevent the rod 73 from escapingfrom said recess excepting when moved endwise.

77 represents an adjustable block carried by the plate 21, against whichthe front end of the heel rests. 78 represents a rod pivoted in thebrackets 20. A lever 79 is secured to this rod (see Fig. 4) and carriesat its free end a finger 80. An arm 81 is secured to this rod inposition to be engaged by a lug 82 on the rod 57. The free end of thefinger is arranged in an aperture in .the plate 21. The arrangement issuch that as the knife 72 returns to its initial position the finger bymeans of the arm 79 and its connections is actuated to engage the underside and throw it out of the machine.

represents a bracket carried by the upper part of the standard. A pintle91 is mounted in the end of this bracket, and, upon the pintle 91 ispivoted a sleeve 92, having two arms 92 and a finger 92. A clamp 93 ispivoted to the end of one of the arms 92 over the heel 28. The end ofthe other arm 92 is provided with a shoe 94, arranged to be engaged by aroller 95 on the jaw 22. The arrangement is such that when the jawadvances to grip a heel-blank the clamp 93 is forced upon the top of theblank, (see Fig. 1,) and vice Versa. The clamp 93 is concavcd on itsunder side (see Fig. 6) in order not to interfere with the action of theknife. A spring 96 is connected at one end to the finger 92" and at itsother end to the bracket 90.

The spring 96 serves to hold the clamp 93 upon the heel 28, while theroller 95 serves to lift the clamp after the cutting operation to permitthe ejectment of the heel by the finger 80.

The parts are so timed that the machine automatically stops with theknife 7 2, finger 80, clamps 93 24: 22, and other partsin initialposition ready for the reception of a fresh blank.

Having thus explained the nature of the in-' plane of the out of theknife during its stroke.
